For example, there is a gap 281 between the second connecting lug 280 and the second frame body 270. The second frame body 270 is pivotably located in the first through hole 221, so the first frame body 220 extends into the gap 281 Inside. The positioning part 300 is located in the first through hole 221 and fixedly connects the fixing member 400 and the second frame body 270 so as to be interlocked with the second frame body 270.

The positioning part 300 includes a column 310 and a plurality of (for example, six) slots 320. The slots 320 are recessed on one end of the column 310 in sequence and substantially surround the axis 221A of the first through hole 221, and each slot 320 is simultaneously formed on the end surface 311 of the column 310 facing the second frame 270 And on the peripheral surface 312 surrounding the cylinder 310. In this embodiment, the slots 320 are equally spaced around the axis 221A of the first through hole 221, however, the invention is not limited thereto. The fixing member 400 is located on the second frame 270 and is switchably inserted into one of the slots 320.

More specifically, in this embodiment, but not limited to this, the second frame body 270 includes a first groove 274, a second groove 275, a second through hole 272 (FIG. 3A) and a plurality of (For example 6) slot 271. The first groove 274 is recessed in an end surface 273 of the second frame body 270 facing away from the first support frame 220, and is used to receive the fixing member 400. The second groove 275 is recessed on the other end surface of the second frame body 270 and is disposed opposite to the first groove 274 to receive the positioning portion 300. The second through hole 272 is located on the bottom surface of the first groove 274 and connects the first groove 274 and the second groove 275 and is coaxial with the first through hole 221. In other words, both the fixing member 400 and the positioning portion 300 are integrated in the second frame 270. The slots 271 are recessed on the end surface 273 of the second frame body 270, substantially surrounding the axis 272A of the second through hole 272, and connected to the second through hole 272 through the first groove 274. Each slot 271 is coaxially aligned with one of the slots 320. In the present embodiment, the slots 271 are equally spaced around the axis 272A of the second through hole 272, however, the invention is not limited thereto. The shaft module 200 covers the gap 271 and the first groove 274 of the second frame 270 with the top cover 201.

The fixing member 400 includes an insert body 410 and an extension rib 430. The insert body 410 is removably located in the first groove 274 of the second frame 270. The extension rib 430 protrudes from one side of the insert body 410, is located in the second groove 275, and is switchably inserted into the slot 271 and the slot 320 coaxially aligned with each other. In this way, the user can identify the corresponding slot 320 by selecting a specific slot 271, and allow the extension rib 430 of the fixing member 400 to be correctly inserted into the corresponding slot 320, thereby reducing unnecessary operation time.

The fixing member 400 further includes a fixing bolt 500 and an elastic element 530. The fixing bolt 500 locks the plug-in body 410 of the fixing member 400, the second frame body 270, and the positioning portion 300 together. More specifically, the pillar 310 has a through hole 330 that penetrates two opposite ends of the pillar 310. The plug body 410 of the fixing member 400 has a screw hole 420, and the screw hole 420 penetrates two opposite ends of the plug body 410. The fixing bolt 500 passes through the screw hole 420 of the fixing member 400, the second through hole 272 and the through hole 330 of the positioning part 300, so that the plug-in body 410, the second frame 270 and the positioning part 300 are locked together as one. The bolt head 520 of the fixing bolt 500 is located outside the screw hole 420 and covers the screw hole 420. The elastic element 530 is located in the first groove 274 and elastically abuts against the second frame 270 and the fixing member 400 for pushing the card body 410 out of the first groove 274.

The elastic element 530 is, for example, a coil spring, which is located in the insert body 410 and surrounds the stud 510 of the fixing bolt 500. One end of the elastic element 530 is directly connected to the insert body 410, and the other end of the elastic element 530 is directly connected to the bottom surface of the first groove 274 of the second frame 270. As such, when the fixing bolt 500 fixes the fixing member 400 When locked to the positioning portion 300, the fixing member 400 and the second frame 270 compress the elastic element 530, and allow the elastic element 530 to store a resilient force in the first groove 274 of the second frame 270.

In addition, in this embodiment, the second bracket 260 further includes a damping member 600. The damping member 600 is located in the first through hole 221, fixedly connected to one end of the positioning portion 300 opposite to the second bracket 260, and directly presses the inner wall of the first through hole 221. In this way, when the second bracket 260 pivots relative to the first bracket 210, since the damping member 600 can rub the inner wall of the first frame body 220, the damping member 600 can reduce the second frame body 270 relative to the first frame body 220 Pivot speed.

As shown in FIGS. 2 and 3B, the first bracket 210 further includes a limiting portion 240. The limiting portion 240 is located in the first through hole 221. For example, the limiting portion 240 is a side wall of the inner flange 250 of the first through hole 221. The positioning part 300 further includes a stop 350. The stop 350 protrudes from the outer wall of the cylinder 310. Therefore, when the second bracket 260 rotates in the first through hole 221 relative to the first bracket 210, the positioning portion 300 is linked with the second bracket 270. At this time, once the stopper 350 of the positioning part 300 moves to one of the limiting parts 240, the limiting part 240 blocks the positioning part 300, thereby restricting the second frame body 270 from continuing to pivot. Therefore, when the second bracket 260 pivots relative to the first bracket 210, so that the stopper 350 of the positioning portion 300 moves to the limit portion 240, the second bracket 260 drives the temple 120 to extend to the end, so the second The connection lug 280 and the first connection lug 230 have a maximum included angle θ 1 (FIG. 4A ). The maximum included angle θ 1 is approximately equal to the maximum abduction amplitude from the temple 120 to the frame 110.

FIGS. 4A to 4C are operation diagrams of the continuous use of the rotation axis module 200 of FIG. 1 to adjust the maximum angle θ 1 between the lens frame 110 and the temple 120. As shown in FIGS. 4A and 4B, when a user wants to adjust the hinge module 200 to change the mirror At the maximum distance G between the legs 120 (Figure 1), the user first removes the top cover 201 and loosens the fixing bolt 500 of each hinge module 200. At this time, the restoring elastic force of the elastic element 530 (refer to FIG. 3A) is directed away from the first bracket 210, and the card body 410 is pushed out of the first groove 274 of the second frame 270 to speed up the user's operation time.

As shown in FIGS. 4B and 4C, since the insert body 410 of the fixing member 400 has been pushed out of the first groove 274, the user can rotate the fixing member 400 and choose to allow the extension rib 430 to pass through the other slot 271 again Insert into another corresponding slot 320 (Figure 3B). Thus, as shown in FIGS. 1 and 4A, when the temple 120 is abducted relative to the frame 110 (FIG. 1), the maximum included angle θ between the second connecting lug 280 and the first connecting lug 230 described above 1 can be changed, which means that the maximum abduction range of the temple 120 to the frame 110 can be changed, so that the user can further change the maximum distance G between the temple 120 that is abducted to the bottom to match The size of the head of the person.

It should be understood that, in this embodiment, since the six slots 320 are equally spaced around the axis 221A of the first through hole 221, there is an included angle of 60° between any two slots 320. Therefore, the user can choose to insert at least one slot 320 forward or backward to adjust the maximum abduction range of each temple 120 to the frame 110. However, the invention is not limited to this.

In this way, with the structure described in the above embodiment, the user can selectively adjust the fixing member 400 to be re-inserted into another slot 320, so that the maximum abduction width of the temple 120 to the frame 110 can be changed, and then adjusted The maximum distance G between the temples 120. Therefore, the wearable device 10 can be worn on users with different head sizes.

Finally, the above disclosed embodiments are not intended to limit the present invention. Anyone who is familiar with this skill can be protected and protected from various changes and modifications within the spirit and scope of the present invention. Invented. Therefore, the protection scope of the present invention shall be subject to the scope defined in the appended patent application.
